lApplication led April 12, 1916. Serial No. 90,600. Y

To all whom it may concern:

Be it known that I, GEORGE GLAUDEL, a citizen of France, residin at Los Angeles, in the county of4 Los Ange es, State of California, have invented new and useful Ini' lprovements in Silvering-Tables, the following is a specification.

of which This invention relates to improvements in silvering tables and particularly in such silvering tables as set forth in my Patent No. 794,858 of July 18th, 1905.

In my Patent No. 7 94,858 I have described a mechanism in which there is a leveled surface and av mechanism for holding Aa glass plate up' against that leveled surface and for then holding the plate in its leveled.l position when the leveled surface is re-` i moved. In such a combination as described in my said patent, my present improvement is directed particularly to the means for raising the glass plate against the previously leveled surface and for holding theV glass plate in its leveled osition. l

It is an object of this invention to provide a simple and effective means for attaining the ends stated,v and it is also an object of this invention to provide a means for accurately holding the glass plate in its lev- "1 eled position without any chance of the glass plate moving out of its proper position.

I now proceed to describe as much of the derstanding of my present improvement and l 'then proceed to a detailed description of the itself. 'I refer to the accomimprovement panying drawin s which, .for the `purposeof this specication, I 'have illustrated my now preferred form of silvering table.

, In thesedrawings Fig. 3 is a detail plan, away and'in section taken as indicated byl line v Figure 1 is a vertical cross'section ofmy improved table, Fig. 2 is apartial longitudinal sectionof the same; with'parts broken 3-3 on Fig. 2, Fig. 4: is an 'enlarged detail section taken as indicated by line 4.-4; on

' In, the drawings-.the numerallO desig- 'nates a suitable box structure having in its lower portion vas or'the catch the water orother fluid with which the glass plate or'plates 13- are washed before the silvering operation takes place.-

, tal shaft 18 centrally of t f position,

'a partial endelevation the beams 21- are the lheating coils'll and having provision, `asat 12, for extendin a canlike over the heating coi s 11 to'.-

Suitable cross beams or other supports 15 are builtinto the box; and on these beams I place stringers 16 as illustrated, these stringers carrying the glass raising and supporting mechanisms,` as will be hereinafter described. I provide. suitable glass supporting frames 17 adapted to support the glass plates l13. These fra-mes 17-'are pivoted at one edge. on the shaft 18 and their other edges rest upon the suitable supporting brackets 19. I preferably place the horizong n e table structure and pivot the oppositely disposed frames 17,

17 to this one shaft. The means now to be described operates to raise the outer edges of the glass supporting frames to tilt the-glass plate, so that it may-.be cleansed and washed .any position and to thus hold the movable edges of the glass supporting frames in any veither the position shown in the drawing or in a raised position to tilt the glass plate. v f

The glass plate or-plates being placed von the supporting frames, the frames are easily and quickly inclined to the most advantageous position for cleansing and washing the plates. After cleansingand washing, the

plates are let down to their normal position and are ing. A 1 Y I provide longitudinal ways 20 along the opposite longitudinal sides of the box or table and the leveling beams or bars 21 are supported between these ways, each beam at its ends for rolling suplIn their normal positions all at one end of the table, the right hand endin Fig. 2. The number of thesebeams depends-upon the length of the table and upon the distancedesired betweentli'e beams when having rollers 22 port in the ways.-

the table'. A rope or cable 25 passes through the beams and .any suitable rovision may be made for moving drums .26 at the ends oit the table.

the cab e endwise, as This then ready for leveling and silverspaced apart along cable is secured to the first beam 21 by any suitable means, as by collars 27; so that the first beam moves with the cable. Connective means is provided between the beams consisting of two links 28, these links havingl feet or lugs 29 which prevent their movement to straight line position. When the first beam is drawn out over the table the second beam follows at the distance determined by the links, and then the remaining beams follow in the same manner. When the first beam-is drawn backthe links collapse or fold on each otherand the beams then move one against the other and all move back to the end of the table shown in (gJn the opposite longitudinal sides of the,

table I place leveling plates 30 y which plates 30 are initially carefully leveled; so that when the beams rest upon their upper edges they are in exactly leveled position. ways 20 are mounted upon vertically sliding racks .31 worked by pinions 32 in the manner explained in my said patent.; so that the ways may be lifted and the beams 21 may be lifted off. the leveling plates 30.

In the'operation of my device the glass is placed at 13 upon the frames 17 and initially cleaned or washed in the manner liereinbefore explained. The leveling beams are then run out over the glass and are lowered onto the leveling plates 30. Their lower surfaces then present an accurately leveled surface against. which the glass plates may be raised. The improved mechanism for raising and holding these glass plates in position is the' particular subject f matter of this specification and the followi ing claims. I have shown a plurality of raising and supporting mechanisms 50 "and shall now describe one of them in detail.

Each of these mechanisms embodies a suitable bearing stand 51 carrying a vertically movable plungerI 52 having a glass supporting foot 49 upon its upper end. This plunger 52 is enlarged at its lower end as shown' at 52a; and around this enlarged portion I place a split ring clamp 53. This clamp is conned vertically between the two parts 51a of the bearing stand 51. Under normal conditions this clamp will not grip the plunger 52 but will allow the plunger to move freely. The plunger is normally moved upwardly by the operation of a weight 54 The shown in Figs. 1 and 2. After the glass plate is in position and the leveling bars are properly placed on leveling plates 30, then the bars 60 are moved to withdraw the wedges from beneath the weights 54; with 70A the result that the weights act to force the Vplungers upwardly against the glass plates and lift the glass plates against the leveling beams 21 the beams being sufficiently heavy .I to prevent their being lifted). By the same act which withdraws the vwedges from beneath weights 54 the clamps 53 are caused to l tightly grip the plungers 52.'` This `is accomplished bythe operation of a clamp arm 70 pivoted at 71 and having a nose 72 bearso This movement compresses the ASpring 75,

the spring 7 5 forming the connective means between bar 60 .and lever 70.- The spring 75 lies around a rod 76 .which is connected at 77 to the lever 70 and passes loosely through a lug 78 on theside ofbar 60. 95

When the bar 60 is moved in the direction opposite to -that indicated then the lever 70 1s released and clamp 53 is released with the result that the plunger is free to move as has hereinbefore been explained; but when the bar 60 is moved in the direction indicated then the clamp 53 tightly grips the plunger, 1nr whatever position the plunger i;

happens to be, and holds it and the vweight 54 immovable.

the accurately leveled lower surface of the beams, and the plungers having been grip- The plungers having been v movedup to support the glass plate in posi-,r Vtion withvits upper surface pressed against ped and held in their respective positions,

the glass plate is now supported by the plungers in exactly leveled position. The leveling beams 21 may now be raised by raising the ways 2O and the beams removed from over the glass plates. The operation of sil- 4vering may then be carriedon efficiently as the glass plates are held zontal position.

My improved mechanism providesfor eilin. accurately horiciently raising the glass plates against the leveling surface and for efficiently and accurately holding the plates in that position.

When the plungers are raised against the glass and the glass is raised against the leveling beams, then Athe clamps grip and hold the plungers in precisely the position at which the plungers then stand. Upon removal of the leveling beams there is'no movement whatever of the plungers;. and,

therefore, there is no movement whatever glass plate from proyjierly leveicd esitin. i

Having described the preferred orm of my invention, l claim:
